About this game
You are the captain of the USS Astrea, a cargo ship stuck on the most boring route in the Helios Belt. Until a distress signal changes everything.
Astrea Protocol is a narrative, choice-driven game inspired by the great interactive messaging stories. You don't move a character: you talk to your crew. Yuki, Vera and the rest of the team message you, and every reply you send pushes the story toward a different fate.
A CONVERSATION THAT UNFOLDS IN REAL TIME
When a crew member heads down to the reactor and says "I'll check back in 45 minutes," those 45 minutes actually pass. Close the app, put your phone away, live your day: the ship pings you with a notification when something happens.
SCIENCE FICTION WITH YOUR HEART IN YOUR THROAT
What begins as a routine cargo run becomes a slow descent toward something that shouldn't exist in the Helios Belt. Suspense, impossible decisions, and a dread that builds word by word.
YOUR CHOICES MATTER — FOR REAL
The story branches toward 14 endings. The tone you speak in, who you choose to trust, and the risks you take decide who makes it home… and who doesn't. Every playthrough is yours.
HOW IT WORKS
• ACT I is free to play in full — a complete arc with its own endings.
• A single purchase unlocks the rest of the story: Acts II through VI and all 14 endings. Pay once, yours forever.
• No ads. No subscriptions. No repeat purchases.
• Offline: once installed, play with no internet.
Come aboard the USS Astrea. The crew is waiting for your reply.
